development of a useful procedure for the removal of thioacetals and thioketals using Dess-Martin periodinane (DMP) reagent. In contrast to existing methods, this protocol offers general reactivity, compatibility with a wide range of functional groups, and convenient reaction times. Also discussed are chemoselectivity experiments involving functionalities that may be subject to oxidation by DMP, qualitative

The aldehyde of compound 2 is more reactive than the ozonide in the carbon-carbon bond formation reactions. The ozonide is stable under the Lewis acid, radical and organometallic conditions where aldehyde reacts efficiently. The ozonide moiety can be considered as a synthon or protecting group for the aldehyde and carboxylic acid.
